After you install McAfee VirusScan Enterprise Version 8.0i, your Microsoft Windows Server 2003-based or Microsoft Windows 2000-based computer may occasionally stop responding. You may receive error messages that are similar to this in the System log: The server was unable to allocate from the system nonpaged pool because the pool was empty.

This happens because a leak occurs in the system non-paged memory pool. The pool tags that indicate the location of the memory leak are McOp and McFN.
